Setup docker bind to allow a selenium container to see an nginx container.

[rquadling]

Hi.

I'll say straight away, I don't know or understand bind and/or linux networking.

My requirement is to have the browser that runs inside a selenium container have access to an nginx server running in another container. We are using selenium for some of our automated testing and am trying to make things a little simpler for the developers who need to build and run the end-to-end testing.

It sounds simple enough. But I don't even know how to ask the question properly.

Currently (without the bind container), we have to manually add every domain and subdomain to the links section in our docker-compose.yml file for the nginx service for the browser inside the selenium container to see things.

This would be great, but we want to use a wildcard subdomain sort of thing, so any subdomain of test.local (for example) would be sent to the nginx container, where nginx picks up the request and uses PHP-FPM to handle it. The PHP code deals with extracting the right processing for the subdomain. A multi-tenanted application with subdomain partitioning. Not particularly unusual.
